Clemens Backes af7c307d82 [wasm] Introduce AssemblerBufferCache
This introduces an AssemblerBufferCache class which will (later) cache
the backing store of AssemblerBuffers. This is needed for PKU-protected
assembler buffers, which are expensive to allocate and deallocate.

For now, the AssemblerBufferCache does not do any caching, this will be
added in a follow-up CL.
